Question

I have two functions and i want to make it like one.

function 1

public function getAlliancesList($pageIndex, $pageSize)
{
    return $this->provider->fetchResultSet("SELECT  a.id, a.name, a.player_count, a.rating    FROM p_alliances a    ORDER BY a.rating DESC, a.player_count DESC, a.id ASC    LIMIT %s,%s", array($pageIndex * $pageSize, $pageSize));
} 

function 2

public function getAllianceAverage($allianceId)
{
    $row = $this->provider->fetchRow("SELECT AVG(p.total_people_count) as average FROM p_players p WHERE p.alliance_id = '%s'", array($allianceId));
    return intval($row['average']);
} 

Basically I want to join function 2 into function 1 so I don’t need 2 query’s and I can then call that one function on the template file like $this->datalist->row['average'] if this is even possible.

I’ve tried a lot of ways to get the two queries to work together but to no avail so any help would be great.

EDIT:

What i want is to include the alliance id in getAllianceList function

this is how we tried till now:

public function getAlliancesList($pageIndex, $pageSize)
        {
            return $this->provider->fetchResultSet("SELECT *
FROM `p_alliances`
JOIN `p_players` 
ON `p_players`.`id` = `p_alliances`.`id`  LIMIT %s,%s", array($pageIndex * $pageSize, $pageSize));
        }

Answer 1

SELECT
    a.id,
    a.name,
    a.player_count,
    a.rating,
    AVG(p.total_people_count) AS `average`
FROM p_alliances a
    INNER JOIN p_players p ON (p.alliance_id = a.id)
GROUP BY a.id
ORDER BY a.rating DESC, a.player_count DESC, a.id ASC
LIMIT %s,%s

If there could be 0 players you might want to change INNER JOIN to LEFT JOIN, but it may impact performance in mysql.
